Question:
What is the polarity of the 20247 Battery Disconnect Switch?
Answer: The 20247 Battery Disconnect Switch is designed for negative polarity systems, which is standard for most automotive and marine applications.

Question:
How do I install the 20247 Battery Disconnect Switch?

Always consult a professional if unsure about the installation process. -
Question:
What does the lock-out plate do?
Answer: The lock-out plate feature of the 20247 Battery Disconnect Switch enhances safety by preventing accidental activation. It allows users to lock the switch in the 'off' position, ensuring that no one can inadvertently connect the battery while maintenance or repairs are being performed. This is particularly useful in RVs and boats where safety around electrical systems is vital. With this feature, you can have peace of mind knowing that the battery will not engage until you are ready. -
Question:
Can this switch help in preserving battery life?
Answer: Yes, using the 20247 Battery Disconnect Switch can significantly aid in preserving battery life.

What would be some common applications for this disconnect switch?
Answer: The 20247 Battery Disconnect Switch is commonly used in various applications, including automotive, marine, and recreational vehicles. It's perfect for RVs where electronic systems remain powered even when parked, preventing battery drain during long periods of inactivity.
